The celeb-studded Hell’s Kitchen hot spot Club Pacha got another black eye over the weekend when cops were called there twice to bust two patrons on assault charges, police said.

At 3 a.m. Saturday, police arrested Andrew Williams, 21, of Bogota, NJ, after he allegedly punched Zogher Ahmed, 19, in the eye. Ahmed, who lives in the Big Apple, told cops he didn’t know Williams and didn’t provoke the fight.

About 24 hours later, at 2:13 a.m. Sunday, Carlos Melo, 29, who said he was from Seattle, was kicked out of the club but ran back in and hit a 19-year-old woman, Margarita Serrano, in the face, police said.

In July, the club was briefly shut down by vice cops who bought drugs after spending a year posing as clubgoers.

It also has been targeted by the State Liquor Authority in a crackdown on underage drinking.
